Political Parties and Civility in Parliament: The Case of Australia from 1901 to 2020.

Incivility in parliaments is always prominently displayed in media reports, often with the implicit or explicit commentary that the situation is getting worse. This paper processes and analyses the records of verbal interactions in the Australian Parliament for over 100 years to provide a first approximation on the evolution of civility. It provides a framework for understanding the multidimensional nature of civility that examines both 'politeness' and 'argumentation', with the latter grounded in notions of public-mindedness. The analysis focuses on the interactions between parties of the orators and the party in power, the chamber of utterance, and the year. The results indicate that instances of impoliteness have increased since the 1970s but only modestly and remain highly infrequent. Minor parties, particularly those representing right-wing and Green politics are more likely to use dismissive or offensive language than the dominant centre-left and centre-right parties, although direct insults and swearwords are the particular remits of right-wing 'system-wrecker' parties. All these minor parties, nonetheless, also display higher levels of argumentation in their interventions. This combination of aggressive language and increased argumentation highlights the pressures on minor parties to convey their points in a forceful way, a challenge that is particularly pressing in two-party systems like the Australian one.
